My 1957 21 inch Invictus TV. It is missing the back cover. This same model of TV appears in many scenes of the 1957 Brazilian movie "Absolutamente Certo" a film whose plot revolves around a television quiz show.

That's the biggest transformer I have ever seen.

Probably for both 50 and 60 cycle. The Canadian 25 cycle transformers are larger yet.
The CRT looks like a 21ALP4. It always seemed strange, that the foreign TV manufacturers didn't use a cover on the CRT socket.
Set uses a 5U4 an a few 6SN7's. :thmbsp:

Toward the end of the CRT era in the US, many TV manufacturers used a printed circuit board integrated with the socket for the CRT with the bare pins for the CRT fully exposed.

I suspect the Brazilian manufacturer left off the shell to facilitate servicing. Sure beats looking under the chassis for the other end of the CRT leads to measure voltages!

Beautiful set, would ike to have one in my collection!:tresbon:

GE was cheaper still on some sets. I remember hearing that they did not even use a socket in some models...Just the metal pins/solder lugs from sockets.

Some makers (IIRC I think I've seen this on 60's Zenith B&W sets) put exposed terminals for measurement/soldering purposes on the socket.

Does it haves Brazilian made compoments?

At least more than 50% of the components are Brazilian-made, including the CRT, which was made by Invictus itself.
